My first Springfield Garand has a serial number of 7002XXX. Scott Duff's book is only showing serial numbers up to 6099905 in 1957. He does state the book is incomplete. Was there more Garands manufactured after 1957 but not delivered? Is 7mil. that a reliable number? Maybe I got the LAST ONE manufactured. ( wouldn't that be a hoot! ) . Keep 'em in the ten ring!
